T
he demand for tooth-colored restoration has grown considerably during the last decade. The restoration of anterior teeth is a
difficult task, even for an experienced operator. Color is the most important determinant of esthetics. The esthetic appearance
of a restoration should match the surrounding dental tissue. This requires that the optical properties of the restorative material be
similar to that of the natural teeth. Thus, for an acceptable esthetic result, favorable shade matching of the all-ceramic restoration
should be achieved by controlling absorption, reflection and transmission of dental ceramic material. Currently there are many
different ceramic systems that can be used to achieve highly esthetic results. These include metal-ceramics with porcelain margins, In-
Ceram, Hi-Ceram, IPS-Empress, Optec, and CAD/CAM ceramics. All ceramic systems have different composition, microstructure,
crystalline content and phases. Direct transmittance, translucency, opacity and opalescence, all influence the optical properties of the
ceramic restoration. Other factors include the thickness of ceramic, number of firing, glazing, powder/liquid ratio, surface texture and
even the resin shade. This article focuses on controlling these variables to achieve the best possible esthetic result with an all ceramic
system with the emphasis on CAD CAM systems.
